About Viagra

• Prescription-only treatment for erectile dysfunction (ED) in men.

• Viagra is a brand name — the active ingredient is Sildenafil Citrate.

• Standard starting dose: 50mg, taken once every 24 hours. Can be adjusted to 25mg or 100mg based on response.

• Take 30–60 minutes before sexual activity. Effects usually last up to 4 hours.

• Sexual stimulation is required for it to be effective.

• See the patient leaflet for full side effects, precautions, and drug interactions.

• Effectiveness may be reduced by heavy meals, alcohol, grapefruit, or fatty foods.

Sildenafil (the active ingredient) also treats pulmonary arterial hypertension. It’s taken by mouth or via injection. Effects begin in around 20 minutes and last 2–4 hours.

Common side effects: headache, heartburn, flushed skin. Serious side effects may include prolonged erections (priapism), vision changes, or hearing loss.

Important: Do not take Viagra with nitrates (e.g. GTN sprays or nitroglycerin) or within four hours of an alpha-blocker, as this can cause a dangerous drop in blood pressure.

Sildenafil works by blocking PDE5 — an enzyme that breaks down cGMP, which controls blood flow in the penis. Sexual arousal is still required for it to work effectively.
